you don't need a pattern for prefolds. do you have one you can measure? if not i can measure mine to get dimensions.

basically just a square/rectangle with extra layers in the middle third.
Awww.... what I saw must not be a "prefold" then :-( I saw a mummy who had terry nappies that were the triangle kind of shape but curvy edges ITMS? Does anyone have a pattern for those? They looked lovely
